Beginner motorists are always a lot of questions, many of them are due to the existing gaps in knowledge and at the same time fear damage the car (item). Over time, knowledge concerning the auto subject is added, the experience is growing, self-confidence - part of the questions disappears by itself. But there are among them and such that are capable of calling a dispute even among experienced car owners, for example, whether to unscrew the cork when charging the battery. But really, is it necessary? Let's deal with.

Akb varieties and other useful information.

It's not a secret to anyone that car batteries are several species: lead-acid (minority), calcium and hybrid (according to the composition), as well as those serviced and maintained (by constructive features). So the dilemma of the need to unscluded traffic jams can only be set in the case when it comes to serviced standard lead batteries either hybrids, since only these most traffic jams will be present.

All other options for the possibility of topping the water or electrolyte are not provided, therefore there are no special holes.

So, do you need to unscrew the cork when charging the car?

In fact, there is no definite answer.

On the one hand, everything is extremely simple: in the car, the battery is in the car without a disruption of the body's tightness and nothing happens, plus, the engineers are not stupid people, they naturally provided the possibility of reloading and the impact of increased pressure on the walls of the device, it means that the plugs When charging the charger, it is not necessary to clean the charge.

On the other hand, a long time and actively operated battery is not so reliable as new, therefore, how long it can withstand the pressure of vapors secreted by boiling acid unknown, therefore, in order to minimize the risk of a possible explosion, the lids are still recommended to unscrew.

Hence the conclusion:

1. when recharging a new battery is required (for example, from 12.4 V to 12.7 c) a small amount of time with a small current, "covers" do not unscrew;
2. when the battery has a short life, but completely discharged, the plugs can be turned out to measure the density of the electrolyte, when charging, their complete absence is not required, just to weaken a little;
3. when reanimation of a fully planted old battery or its charging - the lids are always unscrewed, non-compliance with this Recommendation is fraught with a rupture of the AKB.

How to unscrew the plugs?

The covers in the serviced devices are different: towering over the surface of the housing and flat, made with it at the same level. The first are twisted simply - a slight movement of the hand, the second is not rarely not amenable to hand, but also a screwdriver. What to do then? Use the primary means is a 5-ruble coin or, for example, the narrow edge of the line, in general, any wide flat object, but most importantly, before proceeding to turning, do not forget to protect yourself with gloves, inside the cans.

A few opinions.

Pavel:

"I am sure to remove, because hydrogen is distinguished. And if there is a bad contact between the banks, it may turn so much that it will not seem little. I prefer to be restrained. Yes, and the electrolyte is expanding, the battery can simply "suffocate". "

Zhenya:

"It all depends on the charger, if you do not have a" doping ", and modern, then the device itself will not allow acid to boil, restricting at the end of the current, so you can not engage with" games "with twisting / twisted."

Sergey:

"In order to know if you need to unscrew the plugs when charging the battery, you only need to examine the latter. If in the side of the side there is a "hole" - you can not open it, if not - be sure to unscrew "!

For many drivers, the question of whether you need to unscrew the traffic jams when charging the battery is not relevant, but for those who will perform this for the first time, read the article will be useful and interesting. From how correctly it will be organized and executed this process, the service life of the starter battery depends. It is possible to completely "handle" or reduce, and, and a strong period of using the battery. So that this does not happen, nothing is needed, compliance with the rules for the implementation of such a procedure.

Whether you need to unscrew the plugs when charging the battery becomes clear after reading this article.

A little bit about the types of batteries

New products are not so often used, so we will stop on long-known and widely used lead acid AcB. They meet several species. The highest distribution was obtained devices from the category of low-service as well. But occasionally you can meet the serviced batteries. Them distinctive feature is the cost, which is somewhat higher than that of the rest.

The advantages of this type of battery are only the fact that it is possible to replace unsuitable cans. To carry out such a procedure, they are filled with mastic, which is influenced by high temperatures It can start melting. As a result of this impact, the insulating properties of mastic are beginning to be lost, and due to this, the currents of the self-discharge increase. More often should control the level of electrolyte, approximately 5-7 thousand mileage kilometers and the discharge of distilled water is required.

The following type implies a number of low-service batteries. The name itself already suggests that they require the smallest attention to check, control and maintenance. The choice of such products is quite large, you can pick up both expensive and not very accumulatory batteries. Plastic housing has high strength. Take water around about 20-30 thousand mileage kilometers.

It is impossible not to say about such a type of products that belong to the maintenance-free battery. When operating such devices, it practically does not have to top up distilled water, it evaporates so little. However, it should be noted the need for careful control over the state of electrical equipment and especially.

About carrying out charging

When using acid acb on the cathode plates, lead sulfates are formation of lead sulphates, and at the same time, energy is started in the form of electrical currents. Because of the electrochemical reactions, there is a significant selection of water, which decreases the density of the compound electrolyte. If instead of the voltage consumption, it will begin the return process, the lead will start recovering, and the electrolyte concentration will be elevated.

To be carried out battery charge, you need a charging current from external source Skip so that it is opposite to its discharge current. As a result, lead sulphate on a positive electrode begins to manifest in the form of lead dioxide. On negative electrodes, lead sulfates become spongy. These processes occur with a significant increase in sulfuric acid, and water in the solution decreases.

When ended full recovery The active masses of both electrodes, the electrolyte has a density as before the discharge starts and ceases to rise further. Only water electrolysis processes begin to occur in banks. Gas bubbles from hydrogen and oxygen begin to be released from the electrolyte. On the one hand, this testifies to the end of the charging process, and on the other, the formation of an explosive mixture begins, which is called "rattles".

If the process is put on a self-shot, there may be exceeded by the permissible pressure of gases in banks and break them. Therefore, it is mandatory to unscrew the traffic jams from cans when charging the AKB in a stationary charger. You need to disconnect the terminals from the battery only after its disconnection from the network, otherwise the spark may occur, and the explosion will follow it. It is impossible to smoke or enjoy open flame closely charged devices.

The process of restoring the capacity of the battery is not complicated. But requires constant monitoring, strict compliance with all rules for the implementation of such works. We hope that you have become clear whether you need to unscrew the plugs when charging the battery. It is best to perform such an air surgery or in a well-ventilated room.

Answer from Sergej Piter.[newcomer]
Needless. But then the akum depends on. If there are holes in the lid with God, on one side it is one side, then you can not open. And so necessary.

Answer from Їїicla[guru]
if there is no possibility to do this, then put a smaller ampere when charging and nothing terrible will not be, the only charging time will increase, otherwise you look at the explosion, there are holes on the old batteries on traffic jams and through them, and where there is an acb Electrolyte leaves boiling.

Answer from Ўry Ivanov[expert]
and on my battery, the plugs are posted. Only on the side there is a damper which and remove when charging

It often happens that access to electrolyte is needed to maintain or diagnose the battery, which is meant to remove the lid.

Batteries are divided into batteries with access to electrolyte and without access to electrolyte. The batteries with access to the electrolyte are installed either corks (unscrewed by a ruble coin or screwdriver), or a single lid plate that can be removed with a screwdriver. Before removing, make sure your battery is not mentioned in the battery list below.

How to remove battery lid Varta, Bosch, Atlas, Delkor, Bost, Banner

If you want to remove the lid from the car battery VARTA, BOSCH, ATLAS, DELKOR, BOST, BANNER - Calm down, you will not do this. If you want to remove the battery lid itself, on which the pole conclusions are facing, then you know, it is hermetically soldered at the factory and does not imply a removal - the battery can be thrown out.

If you want to remove a single plank cover, then it closes the labyrinth system to condensate evaporation that you will also fail to dismantle. But it all depends on what you remove the lid from the battery. If you need to measure the level of electrolyte, you can get by weighing the battery on the scales and comparing the indicators with the new Akb. If you need to measure the density, it will be easier to measure the voltage and calm down. If you need to adddistilled Waters, then you can show the smelting and do thin holes without damaging the labyrinth system, and pour water there with the help of a medical syringe. After the hole is filled, it is necessary to pan.

All about batteries

Battery is chemical source Current, for the proper operation of which certain chemical processes should proceed. In the process of battery discharge, sulfuric acid "sticks" to a negative electrode, forming insoluble lead sulfate, left

Very often from sellers in auto shops you can hear recommendations on hybrid batteries. So what is a hybrid battery? The hybrid battery for the car is outwardly not distinguish between others. acid batteries, not counting the designation on ethics

Today I want to tell you about very simple, but, at the same time, a very comfortable homemade.

I will start in order ... We all go on cars, and we all know that in the car there is a rechargeable battery.
In order for the rechargeable battery for many years faithfully, it is necessary to perform several actions:
1. Monitor the health of the car electrical equipment.
2. Do not allow a "deep discharge" battery.
3. Monitor the level of electrolyte in the battery.

To perform the first condition, it is necessary to simply measure the voltage supplied to the battery terminals from the generator. (On the idling With the "stove" and the headlights of the near light, it should be no less than fourteen volts!)

You can forget about the second condition, if after starting the engine, it works for you every time more than half an hour. (This is, approximately, the time is required to make the battery compensate for the container from the generator spent on the engine launch). If you are mainly "short-run" in the city, then, from running to launch, your battery is confidently moving towards the so-called, "deep discharge" - sharp avalanche-like discharge of the battery to critical low values. I am experiencing an abbus "Deep discharge" not always. And certainly, he will never pass without consequences - even if the battery is restored, part of the container will be lost! Therefore, even if your battery at first glance, it seems "fully charged", and the "Boyko" turns the starter, it is still necessary to take it about once every six months and charge it on stationary charger.

But the third condition is very easy to observe ... It is necessary to turn the tubes from the battery from time to time, to make sure that the fluid level is higher than the package of plates in each "bank" ... (this, of course, does not concern more expensive , "non-serving" batteries, in which there are no traffic jams, and in which the pairs are condensed with a special design and are sent back to the battery).

And so with this, at first glance, a very simple action, we often have problems ...
For the simple reason that the skills of the battery have a specific groove, through which, at first glance, you can unscrew the tube "of anything" ...

In fact, this "of anything" at hand does not turn out to be ... You can, for example, use a coin ... but there is an acid !!! And after use, the coin is already desirable not to put in his pocket ... Eh ... sorry to coin ...)))

Many try to make it with a scolder ... Most often it is not possible to make even very wide scolding, as the plug plastic is very soft, and the groove is cruciform (which is even more weakened by the plug). Usually, the dumping turns, deforming the plastic ....

Below I will describe the manufacture of a very simple and very comfortable key, which will allow you to unscrew the tubes from the battery excluding the contact of the hands with acids, and without breaking the slots of the plugs.

For this we need:

1. M8 washer enlarged.
2. Cork from a plastic bottle.

Once, in search of this very "anything" (about which I wrote above))), I noticed that the enlarged washer M8 is very tight in the grooves of battery plugs, and it is more convenient to use it.

As you know, flat washers in GOST are divided into ordinary and enlarged (in which the outer diameter is three internal)

Here, at its base, I decided to make the key.

To make a comfortable "handle", I decided to take advantage of the usual plug from the plastic bottle:

Washer place in the tube "on the edge":

And fix that completely filling the cork with hot glue:

Everything!!! That's all homemade !!!
After hardening, we get a very comfortable key.

Now, without touching the body rechargeable battery, on the surface of which can be acid, we insert our key in the jam dads and unscrew it:

At the same time, our key is so accurately included in the groove, which is fixed in it quite tightly so that the plug in it remains after turning.
